Just before Christmas I came across RealDraw Pro, fantastic software! I am only just starting to get a hang of some of it's capabilities. One of the most impressive allows wmf files (clipart) to be imported and completely changed using built in styles. This sunburst was created using the 'follow path' tool. Do take a look and try it for 30 days. A brilliant vesatile, stand alone program.
